Ridiculously expensive for each app!!! – Dinosaur Park - Jurassic Dig! Review

My 5 year old loves each of the Yateland Dinosaur apps. He is always begging me to buy the full version of each one at $2.99 for each. There are over 6 Dino apps! Come on! That is really crazy! He plays the free version but they are always doing a plug to buy the full version. Please make this app less expensive or in some kind of a bundle.
